Yomogi Asanaka is a regular high school student who happens upon a mysterious young man named Gauma, who is disabled by hunger. Yomogi offers Gauma a sandwich, which earns Gauma's loyalty to him, as he reveals that he is a "Kaiju User". The next day, Yomogi is asked out on a date by Yume Minami, a strange girl from Yomogi's class who has a reputation for asking boys out on dates and then ditching them. Yomogi, skeptical of the rumors, accepts. Meanwhile, strange phenomena begins to occur around
At the conclusion of the battle, Dynazenon shrinks down into a toy size. Gauma splits Dynazenon's components between himself, Yomogi, Yume, and Koyomi. Meanwhile, Chise finds a mysterious pebble on the ground and picks it up. Gauma tells the others that the Kaiju they just fought was being controlled by the "Kaiju Eugenicists", Kaiju Users like him, and that they will attack the city again, so they must train to better pilot Dynazenon. While Gauma, Yume, and Koyomi are serious about training, Yo
The Kaiju Eugenicists reveal that they and Gauma used to be comrades, and ask him to rejoin their ranks, to which he refuses. Realizing they are at a disadvantage without a kaiju, the Kaiju Eugenicists retreat. The next day, Yomogi meets Yume at school, where she tells him how she and her older sister, Kano, were never particularly close, but Kano went out of her way to invite Yume to her music recital shortly before she died. Yume had been left wondering why Kano reached out to her then, and ge
Yomogi lately finds it difficult to focus on his tasks, and Inamoto surmises that he has a crush on Yume and encourages him to ask her out on a date. Yume meets with Kanae but does not learn much from her, but is pointed towards another classmate, Urita, who should have video recordings of Kano's performances. Later, one of the Kaiju Eugenicists, Sizumu, joins Yomogi and Yume's class under the guise of a transfer student, but appears friendly. He tells Yomogi and Yume that the Kaiju Eugenicists
During another training session, Yomogi and Koyomi test combining Dyna Soldier and Dyna Striker together into Dyna Soldier Striker Combine, but find the combination too top heavy to use effectively. Yomogi and Yume then go meet Urita, who shows them a video of Kano, but does not know much more about her. Koyomi has lunch with Inamoto, as he wonders why she suddenly wants to spend time with him even though she is married. Meanwhile, Chise secures tickets to the Tokyo Beach Land water park. Yume i
In a meeting Yume is disturbed upon the rumors that Kano was being bullied by her classmates which could possibly have led to her committing suicide. However, the video evidence she views is not conclusive and Yomogi feels troubled when Yume starts shutting him out. The Kaiju Eugenicists have their own meeting, with Juuga and Onija advocating for killing Gauma and his friends, but Sizumu believes keeping them alive will benefit kaiju evolution, while Mujina remains undecided. Meanwhile, Koyomi h
Gridknight attacks the kaiju and quickly gains the upper hand, forcing Onija and Mujina to teleport it to safety and retreat. Gridknight then attacks Dynazenon, mistaking it for another kaiju, but quickly withdraws when his energy runs out. Koyomi sees Inamoto's husband caught in the wreckage and goes to rescue him, despite his resentment and jealousy towards him. Gauma, Yomogi, and Yume unsuccessfully search for the kaiju before deciding to stay watch all night to wait for it reappear. Chise an
Sizumu comes across a kaiju, but it is incomplete and deformed, so he decides to ignore it. Koyomi recalls how while he was in high school, he came across Inamoto finding a bag full of money and asking him to run away with her, but he fled in fear instead. Yomogi and Yume try to track down Futaba with little success. Gauma learns about the kaiju and summons the group, and they manage to capture it. Gauma attempts to dominate it, but fails as his power appears to have weakened. The other members
Chise discovers a small, golden dragon-like Kaiju in her room who responds to her commands, which she names Goldburn. While Chise ponders about what to do with Goldburn, Futaba Senda has a meeting with Yume and Yomogi. Yume reprimands Futaba for not being at her sister's side when she needed it and falls into despair, just when Juuga takes control of another Kaiju. Yomogi attends to Yume's request to join the others ahead of her but Gauma sends him back to pick her up. Chise attempts to convince
The Kaiju Eugenicists come across another kaiju and attempt to dominate it, but all of them mysteriously disappear instead. Meanwhile, as the Dynazenon crew are enjoying the day, they are sent into shock as the kaiju makes Yume, Koyomi, Gauma, and Knight disappear one by one. While Goldburn protects Chise and Second, Yomogi leaps into the kaiju's mouth to rescue his friends. Inside, Yomogi finds out that the kaiju has trapped everybody in their own memories. He enters Yume's memory, which takes
After the battle, the Kaiju Eugenicists discover that they are out of Kaiju to fight with and disband. With their mission apparently over, Gauma retrieves Dynazenon from the others, but is disheartened that he never managed to reunite with his beloved Princess. Koyomi decides to look for a job and Chise attempts to return to school, when Knight and The Second reveal to her that they will soon depart to another world, taking Goldburn with them. Yume asks Yomogi to accompany her to visit her famil
